A dog walking service charges a $19 one-time fee, plus $40 per week. The
equation y = 40x + 19 models the cost of using the service. y is the total
cost in dollars, and x is the number of weeks. Kevin estimated the cost of
using the service for 4 weeks to be about $180. Which statement is true? *

Answer:

∠FJG= 135

Step-by-step explanation:

∠FJG + ∠GJH = 168 so

(6x - 15) + (x + 8) = 168

7x - 7 = 168

7x = 175

x = 25

plug it in ∠FJG

6(25) - 15 = 135

Step-by-step explanation:

a2+(48)2=

 502\,\,50^{2}502

Use the Pythagorean Theorem.

a2+2304=a^{2}+2304=a2+2304=

 2500\,\,25002500

Simplify.

−2304-2304\phantom{=}−2304=

 −2304\,\,-2304−2304

Subtract 2304 from both sides.

a2=a^{2}=a2=

 196\,\,196196

a2=\sqrt{a^{2}}=a2

​=

 ±196\,\,\pm\sqrt{196}±196

​

Square root both sides.

a=a=a=

 14\,\,1414

Simplify. Ignore negative root, as length must be positive.

Step-by-step explanation:

I'm assuming that non-linear means that there is some type of association between the dots, they are just not in a straight line. Now, they definitely are NOT in a straight line, but they do appear to be falling in an exponential pattern. I would say that this is a non-liner association (exponential decay, to be specific).

Answer: S = 50W + 75

Step-by-step explanation:

I got to this answer by a bit of trial and error.

I first noticed that the relationship between the balance in the savings account from week to week was increasing by 50.

But when I tried W = S + 50, that did not work at all because when I plug in 125 for S, I should get 1 for W, but instead I get 175. So I realized I had something backwards.

I then tried listing the relationship as ordered pairs of (W, S).

For example I did (1, 125), (2, 175), (3, 275) and so on. So I thought of S like y and W like x where S is a function of W. I used the equation y = mx +b or S=mW + b as an outline.  I figured that W would have to be multiplied by 50 to get that jump between the numbers in the S column. But I could not do S=50W + 125 because if W = 1, S = 175 when S should equal 125. So I subtracted 50 from the 125 and got 75.  So my final equation was S=50W+75. If you test it with the ordered pairs listed above, you will see that the equation checks out. Try it yourself! I hope this was helpful in some way. Good luck!

Answer:

Se necesitan 15 cajas para almacenar cada alimento por separado.

Step-by-step explanation:

En este ejercicio necesitamos hallar el Máximo Común Divisor entre la cantidad disponible de alfajores y empanadas, cada una de las cuales se almacenan sin mezclar. Para ello descomponemos factorialmente cada número:

Cantidad de alfajores

[tex]450 = 2\times 3^{2}\times 5^{2}[/tex]

Cantidad de empanadas

[tex]105 = 3\times 5\times 7[/tex]

El Máximo Común Divisor consiste en el factor común de cada uno de los productos de números primos:

[tex]M.C.D. = 3\times 5[/tex]

Entonces, cada caja tiene una capacidad máxima de 7 empanadas o 30 alfajores y se necesitan 15 cajas para almacenar cada alimento por separado.

Answer:

Step-by-step explanation:

1) The given line is in "slope-intercept form."

  y = mx + b . . . . . . . . line with slope m and y-intercept b

Comparing this to the given equation, we see ...

  m = 1/2 . . . . slope of given line

__

Two lines are parallel when they have the same slope. Then the value of m that makes the second line parallel to the first is the same value of m:

  m = 1/2

_____

2) Lines with the same slope are parallel, so the value of m needs to match the coefficient of x (the slope) in the given equation.

The Gender Gap in STEM Fields: The Impact of the Gender Stereotype of Math and Science on Secondary Students' Career Aspirations

Elena Makarova1*, Belinda Aeschlimann2 and Walter Herzog3

1Institute for Educational Sciences, University of Basel, Basel, Switzerland

2Swiss Federal Institute for Vocational Education and Training SFIVET, Bern, Switzerland

3Institute of Educational Science, University of Bern, Bern, Switzerland

Studies have repeatedly reported that math and science are perceived as male domains, and scientists as predominantly male. However, the impact of the gender image of school science subjects on young people's career choice has not yet been analyzed. This paper investigates the impact of the masculinity image of three school subjects—chemistry, mathematics, and physics—on secondary students' career aspirations in STEM fields. The data originated from a cross-sectional study among 1'364 Swiss secondary school students who were close to obtaining their matriculation diploma. By means of a standardized survey, data on students' perception of masculinity of science school subjects were collected using semantic differentials. The results indicate that for both sexes, math has the strongest masculinity attribution, followed by physics as second, and, finally, chemistry with the lowest masculinity attribution. With respect to gender differences, our findings have shown that among female students, the attribution of masculinity to the three school subjects does not differ significantly, meaning that female students rated all subjects similarly strongly as masculine. Within the group of male students however, the attribution of masculinity to math compared to chemistry and physics differs significantly, whereas the attribution of masculinity to chemistry and physics does not. Our findings also suggest that gender-science stereotypes of math and science can potentially influence young women's and men's aspirations to enroll in a STEM major at university by showing that a less pronounced masculine image of science has the potential to increase the likelihood of STEM career aspirations. Finally, the paper discusses ways of changing the image of math and science in the context of secondary education in order to overcome the disparities between females and males in STEM.

Answer:

3x³ + x² + x + 1

= 3x³ - 3x² + 4x² - 4x + 5x - 5 + 6

= 3x²(x - 1) + 4x(x - 1) + 5(x - 1) + 6

= (x - 1)(3x² + 4x + 5) + 6

but 3x³ + x² + x + 1 = (x - 1).Q(x) + R

=> Q(x) = 3x² + 4x + 5

R = 6

Answer:

The binomial in expanded form is [tex](0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}[/tex].

Step-by-step explanation:

The Binomial Theorem states that a binomial of the form [tex](a + b)^{n}[/tex] can be expanded by using the following identity:

[tex](a + b)^{n} = \Sigma \limits^{n}_{k = 0}\,\frac{n!}{k!\cdot (n-k)!}\cdot a^{n-k}\cdot b^{k}[/tex] (1)

If we know that [tex]a = p = 0.3[/tex] and [tex]n = 5[/tex], then the expanded form of the binomial is:

[tex](p+q)^{n} = \frac{243}{100000} + 5\cdot \left(\frac{81}{10000} \right)\cdot q + 10\cdot \left(\frac{27}{1000})\cdot q^{2} + 10\cdot \left(\frac{9}{100} \right)\cdot q^{3} + 5\cdot \left(\frac{3}{10} \right)\cdot q^{4} + q^{5}[/tex]

[tex](0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}[/tex]
